i Description.

The apparatus heieindisclosed is principally used in'printing Vpresses to imprint progressively, increasing or decreasing nu inerals successively. f

To this end an approved ormot numbering mechanism, wherein printing wheels such as indicated by the numerals 10,V 11,12, V13, 14 and 1 5, are employed.- The said wheels are rotatively mounted upon a shaft 16 upon which is `pivotally,l mounted a swing 17.

The arms 18 and 19 pivoted on the shaft 16' support the cross bar of the swing 17. A shaft 2O is mounted onthe arms, and a pawl 21 is'secured thereto. .The pawl is provided with various lengths otteeth 22l which successively drop into the'deepratclietv vtooth with which each ofthe Wheels is proy 7 is a horizontal section taken on the lin-e 7 7 in Fig. 5.

APPARATUS.

SerialNo. 676,475.

Each wheelv is provided with a series ofk tenV embossed numerals, arranged troni zero to nine inclusive. The `wheels are-ro t'ated step by step successively as the pawl advances and recedes and each` wheel moves thru one space as the preceding wheel makes a complete revolution.

To rock-the swing 17 and pawl 21 con nected therewith the arm 18 is provided with a circular extension 23, shaped to4 eX- tend between the bracket arms 24 of a reciprocating plunger 25. The plunger 25 makes provision for installing the variable type heads 26. This is bestshown in Figuresl and 5 of the drawings. 1

A T-slot is 'formed in the top of the plunger 25. Under the overhang edges27, the flanges 28 extend. One of the ianges 28 has suitablyl located thereina niche to receive the end of a'detentspriiig 29 which is mounted in a groove formed in the side of the vsaid plunger.

To remove the type head 26 the tree end ofthe detent spring 29 is retracted to release the said type head when the same may be withdrawn from the T-slot wherein it has been held.

AThe plunger 25 is normally extended beyond the ybed of :the type form. In the present constructiomvthe plunger rests or vided.

is cushionedl upon vthe spiral spring 30; l The spring 30 is vhoused within a bore formed* wit-hin the plunger-25 to constitute a guide for the spring case31'. The case 31 is yretained in the plunger'25lby a bi'turcated- U- shaped slide. The slide 32 isfbest shown'in the plunger 25 and in cut-away sections 33 in the sides ot' the case 31.

Figures 5 and 7 Vof the drawing. The slide 32 rests in a groove yformed inthe vwall 'of The moving members of the apparatus `*heretofore described are mounted in a housing formed by an open-centered base'34 having atone end thereof theupstandingside 35 at one end to support the Vshaft 16, the oppositeend thereof is supported by an upstanding partition 36, asis best seen in' Figures 1 and 3 ofthe drawings. v

The partition 36 in the present invention orins one sideot a boX in which the plunger 25 is mounted in service. yThe plunger 25 is held within the box formed by the said" i partition 36 and the sides'37 and 38, byV a spring closedgate 39. VThe gate 39 as shown in Fig.'2 of the' drawingshas a closure iie spring 40 whichsurrounds theV hinge pin'of y lle ifi)

f being outwardly flared.

the gate 39. The spring 40 is sufficiently strong to prevent the accidental or unintentional removal of the plunger 25.

The overhanging side 41 on the said gate furnishes means for opening the same for the removal and replacement of the plunger 25 and also acts as a lock when the machine is clamped in press by furniture which bears on side of case.

With an apparatus constructed and arranged as described, it is obvious that the type head 26 may be quickly and readily changed for replacement by holding back the end of the detent spring 29, while the said head is pressed out of engagement with the overhanging edges 27 of the plunger 25.

Vhen the type head is inserted in the T- slot it is quickly adjusted in place, the detent 29 striking into the niche in the flange 28 of the said type head. Y

As seen best in Fig. 6 of the drawings, provision is made for centering the type head by means of the spring 29, the sides of the niche into which the said spring drives rlhis flared construction presents a rigid setting of the type head. Y

To displace the spring 29, the end of the flange 28 having the niche cut therein, is rounded off or chamfered, as can be seen in Fig. 6. This portion of the flange 28 wedges under the free end of the spring 29, displacing it until theniche in the flanges registers with the spring to permit its entrance thereinto.

The type head being place-d in position, the plunger 25 carrying thesame is placed in operating position, the gate y 39 being opened to admit the plunger between the sides 37 and 38. lVhen the plunger is placed between the sides 37 and 38, it isso guided that the arms 24 pass to the opposite sides of the circular extensionl 23 and rest on the edges thereof. The bottom of the spring casing 31 rests on the base of the housing 34, as can be best lseen in Figures 2 and 3 of the drawings. Y Y

The spring 30 when not compressedextends the plunger upward until the slide 32 engages the upper edge of the cutaway sccrlfhe apparatus in this condition is placed in a printing press form lfor operation. l i l It will be observed that as the type head 26 is forced upon the worlr being printed, the plunger contracts the spring 30 until the embossed type membersrwith which the wheels 10 to 15 inclusive yare provided press upon the said work. Vith the relative depression of the plunger 25, the swing 17 and pawl 21l mounted thereon is retracted about the shaft 16, the said pawl passingover detents or ratchetteeth formed integral with the said wheels 10 to 15. `When now the pressure incident to the operation of printing rclieved from the plunger 25, the said plunger is lifted by the spring 30 and the bracket arms 24 engaging the circular extension 23 rotates the arms 18 and 19 and advances the swing 1? andV pawl connected therewith. rlhis pawl now engages, if permitted, the wheels 10 to 15 inclusive with which it is associated.

lf it becomes necessary or desirable to replace the type head 26 or to remove the plunger 25 for substitution thereof, this is easily and quickly accomplished by taking the housing 34 from the printing forni when by throwing back the gate 39, the. plunger may be withdrawn from the box partly formed thereby and another can be placed in its position with ease and celerity.
